What is the purpose of an antiglycolytic agent?

The purpose of an antiglycolytic agent is to preserve glucose levels in blood samples. Glycolysis, the metabolic pathway that breaks down glucose for energy, can occur in blood samples after they are drawn. This process can lead to a decrease in glucose concentration, which can affect diagnostic test results. By using an antiglycolytic agent, such as sodium fluoride, the breakdown of glucose is inhibited, ensuring that the glucose levels measured in the laboratory accurately reflect the patient's blood glucose levels at the time of the draw. This is particularly important in tests that require precise glucose measurement, such as glucose tolerance tests or assessments for diabetes management. Ensuring sample integrity in this way is crucial for providing accurate diagnoses and treatment plans for patients.
